AlertArtist is a tweak in Cydia that will change around the looks of your push notifications on your device. There are many options to choose from and you can customize as far as the drop shadow. Changing text, font, and size is another option to choose, and can make your notifications stand out among others. If you do not feel like making your own, there are several push-themes down at the bottom to choose from. Don't like the way your notifications look afterward? No problem, you can set them back to default right within the app. Check out AlertArtist in Cydia for $.99.
